Respuesta :

shrevecfaith
I= 9.95 + .5h

20-35=15
I = 9.95+.5(15)
9.95+7.5
I = 17.45

If you used the internet for 35 hours, your bill would be $17.45

Answer:

The expression is : [tex]9.95 +0.50(h-20)[/tex]

Step-by-step explanation:

The expression representing the charges for h hours of use in one month when h is more than 20 hours is :

[tex]9.95 +0.50(h-20)[/tex]

When h = 35 hours:

[tex]9.95 +0.50(35-20)[/tex]

=> [tex]9.95 +0.50(15)[/tex]

=> [tex]9.95 +7.5[/tex]

= $17.45
